Method of performing cell search in wireless communication system

A method of transmitting synchronization signals in a wireless communication system, performed by a base station, the method comprising:

• transmitting a primary synchronization signal comprising a primary synchronization code (PSC);
• and
• transmitting a first secondary synchronization signal comprising a first secondary synchronization code (SSC) and a second SSC,
• wherein the first SSC is scrambled by using a first scrambling code and the second SSC is scrambled by using a second scrambling code, the first SSC and the second SSC being defined by m-sequences generated by a generating polynomial x5+x2+1, and wherein the first scrambling code and the second scrambling code are defined by m-sequences generated by a generating polynomial x5+x3+1.

A user equipment configured for performing cell search in a wireless communication system, wherein the user equipment comprises a microprocessor that is configured for:

• searching a primary synchronization signal comprising a primary synchronization code (PSC);
• and
• searching a secondary synchronization signal comprising two secondary synchronization codes (SSCs),
• wherein the two SSCs are respectively scrambled by using two different scrambling codes, the two scrambling codes being defined by m-sequences generated by a generating polynomial x5+x3+1, and wherein the two SSCs are defined by m-sequences generated by a generating polynomial x5+x2+1.
